What's a baby Olivia called?

...this was a question Olivia posed last night at dinner. We've been talking a lot lately about what different baby animals are called.

Here's the full conversation:

Olivia: What's a baby Olivia called?

Me: I don't know. What is a baby Olivia called?

Olivia: A Yaya.

Now if anyone doesn't know, Yaya is the name Olivia gave herself when she was just barely 18 months old and the name has stuck until now...now I think she may be moving up to little girl status even in her own eyes.
